Can't hide the top and bottom lines in custom searchBar - ios

Question

I´ve tried to change background color inside class SearchBarView: UIView {}:
searchBar.searchTextField.backgroundColor = .clear
searchBar.backgroundColor = .clear
and tryed something like that inside MainViewController:
searchBar.searchTextField.backgroundColor = .clear
searchBar.backgroundColor = .clear
searchBar.layer.backgroundColor = UIColor.clear.cgColor
but, unfortunately I still see this lines inside my custom searchBar.
How can I get rid of these lines?
My SearchBarView class:
class SearchBarView: UIView {
lazy var searchBar = createSearchBar()
override init(frame: CGRect) {
super.init(frame: frame)
addSubview(searchBar)
searchBar.snp.makeConstraints { make in
make.leading.equalTo(32)
make.centerY.equalToSuperview()
make.height.equalTo(34)
make.width.equalTo(300)
}
}
required init?(coder: NSCoder) {
fatalError("init(coder:) has not been implemented")
}
}
fileprivate extension SearchBarView {
private func createSearchBar() -> UISearchBar {
let searchBar = UISearchBar()
searchBar.placeholder = " Search"
searchBar.searchTextField.font = UIFont(name: "MarkPro", size: 15)
searchBar.searchTextField.backgroundColor = .clear
let textFieldInsideSearchBar = searchBar.value(forKey: "searchField") as? UITextField
let imageV = textFieldInsideSearchBar?.leftView as! UIImageView
imageV.image = imageV.image?.withRenderingMode(UIImage.RenderingMode.alwaysTemplate)
imageV.tintColor = UIColor(hexString: "FF6E4E")
return searchBar
}
}
My MainViewController class:
class MainViewController: UIViewController {
private var searchBarView: SearchBarView!
override func viewDidLoad() {
super.viewDidLoad()
setupSearchBarView()
}
private func setupSearchBarView() {
searchBarView = SearchBarView(frame: CGRect(x: 0, y: 0, width: 0, height: 0))
view.addSubview(searchBarView)
searchBarView.searchBar.clipsToBounds = true
searchBarView.searchBar.layer.cornerRadius = 17
searchBarView.searchBar.layer.maskedCorners = [.layerMinXMinYCorner, .layerMaxXMinYCorner, .layerMinXMaxYCorner, .layerMaxXMaxYCorner]
searchBarView.searchBar.searchTextField.clipsToBounds = true
let directionalMargins = NSDirectionalEdgeInsets(top: 0, leading: 24, bottom: 0, trailing: 0)
searchBarView.searchBar.directionalLayoutMargins = directionalMargins
searchBarView.snp.makeConstraints { make in
make.leading.equalToSuperview()
make.top.equalTo(categoriesView.snp.bottom)
make.trailing.equalToSuperview()
make.height.equalTo(60)
}
}
}

Answer 1

If you want to make the top and bottom border lines on the textfield disappear (the dark gray ones), you will want to tweak the text field's border properties rather than the background colors. Try something like this:
searchBar.searchTextField.layer.borderWidth = 0
or
searchBar.searchTextField.layer.borderColor = UIColor.clear.cgColor
and adapt it to fit how you've set up the relevant subviews in your custom search bar.

Set the searchBar background image to empty. This eliminates all background issues you may have such as unwanted lines. For more info reference Apple docs: https://developer.apple.com/documentation/uikit/uisearchbar/1624276-backgroundimage
searchBar.backgroundImage = UIImage()
